Summary:

• **How the Universe Will Eventually End**: Scientists think our universe won't last forever. Over trillions and trillions of years, all the stars will burn out, black holes will disappear, and everything will become cold and empty in a process called "heat death."

• **What Happens to Everything**: Right now, the universe is expanding and getting bigger. Eventually, all the atoms that make up stars, planets, and even us will break apart into tiny pieces, and nothing new will ever be created again.
